ROTATING GRAIN-M ETER.

SPECIFICATION forming part of Letters Patent No. 484,691, dated October18, 1892. Application filed April 20, 1892. Serial No. 429,852. (Nomodel.)

f all whom it may concern.-

Be it known that I, GEORGE E. WILSON, a citizen of the United States,and a resident of Stillwater, county of Washington, State of Minnesota,have invented a new and useful Improvement in Grain-Meters, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, making part of this specifica- :0 tion.

My invention relates to an improvement in devices for automaticallyweighing and registering grain; and it consists in providing a rotaryself-discharging weighing cylinder or scale, divided diametrically intotwo equal parts, each of which is adapted to receive a larger amount ofgrain on one'side of the line of rotation than on the other side,whereby the cylinder is rotated to discharge and register the grain.

With these ends in view my invention relates to certain features ot'construction and combinations of parts, as will be hereinafterdescribed,'and pointed out in the claims.

Figure l of the accompanying drawings is a side elevation illustratingmy invention; Fig. 2, a vertical section showing the weighing device inconnection with an elevator and bagger. Fig. 3 is a perspective of afragment, showing a portion of detail.

Referring to Fig. 1, A represents the trunk or body portion of themachine, to which the weighing-beam or steel yard is pivotally secured,as shown at a. At the short end of 3 5 the lever or beam B is journaled(see a) a revolving weighing and self-dumping cylinder C, formed by thecircular end boards b, circular sides 0, diametrically opposite, thestraight sides (1, diametrically opposite, and the centrally locateddividing board e, extending from side to side through the line ofrotation, the ends of said board to connect with the sides 0 and d at apoint or points diametrically opposite, by which the weighiug-cylinderis divided 5 into two equal compartments f f, extending from side toside of the axis of rotation. Between the outer ends i and h of thesides 0 and dis provided an opening g, through which grain is admittedto the compartments ff. It will be noticed that the space or holdingcapacity of that side of the compartment ff between the center ofrotation and the circular sides 0 is larger than the space opposite andbetween the sameline and the side board d, thus providing room for agreater weight of grain on the inside of the axis of rotation than onthe outer side, by means of which the rotation of the cylinder in thedesired direction is assured; and to further contribute to that endstrips, asj, are placed near to and on a line parallel with the axis ofrotation, that extend a distance at right angles to the bottom ordividing board e, by which the grain is held to the larger side of thecompartment.

At the upper portion of the trunk A is provided a hopper D, having atits bottom portion an aperture and a closing-valve E, hinged tothe-hopper at one side, the free side to drop into the cylinder when thevalve is open to allow the grain to [low from the hopper into thecylinder. To close the valve, a circular riblc (shown in Fig. 3 and bythe dotted lines in Figs. 1 and 2) is placed on the outside and aboutmidway between the circular sides 0 and extending from the circularsides 0 to the outer edge of the side (I. The outer edge of the rib Itserves to raise up and hold the valve E in closed position when thecylinder is rotated to discharge the grain into the bagholder F or otherreceptacle.

At the side and secured to the trunk A is provided a registering deviceG, which may be of any of the well-known and approved forms, having anactuating-lever m, that is engaged and moved a distance by the pin 'n onthe side I) of the'cylinder. The swinging movement of the lever servesto move the dial-wheels of the register. To hold or lock the cylinderagainst reverse rotation, a gravity-actuated pawl P is pivotally securedto the Side of the trunk A, that will yield to the pressure of the pinit on the forward movement, that will catch or engage the pin on thereverse movement, as shown in Fig. 1.

In operation the grain is raised by the ele- 5 vator H and thrown intothe hopper D, from which it falls into the weighing-cylinder C, thequantity to be determined by the weight L on the beam B, as when theamount of grain is sufiicient to overbalance and raise the I00 weight Lthe cylinder will drop a distance to allow the endt'of the sided to passunder the stop J. The cylinder thus released will be turned by apreponderance of grain on the inside of the supporting-axis one-half ofa revolution, and while so moving the grain will be discharged into thebag-holder F, the register operated to tally the measure of grain thathas passed from the weighing-cylinder to the bag-holder, the cylinderraised up by the weight L into normal position, when the forwardmovement will be arrested by the stop J engaging the front edge of theside d, and to hold the cylinder against reverse rotation the pawl Pwill engage the pin n, as shown in Fig. 1.

Having thus fully described the nature and object of my invention, whatI claim, and desire to secure by Letters Patent, is

1. The combination, with a weighing'beam, of a rotary weighing-cylinderdivided into two compartments extending diametrically from side to side,dividing-board e, and strips j, and

the sides a and d, substantially as described, and for the purpose setforth.

2. The combination, with the body portion or trunk, a weighted beam, anda gravity-pawl pivoted to said trunk, of a rotary weighing-cylinderpivoted to the inner end of said weighiug-beam and divided intocompartments,

each of greater capacity atone side the axis of GEORGE E. WILSON.
